概要

Description

GD25Q16CEIGR is a 16‑Mbit serial NOR flash memory from GigaDevice. It provides non‑volatile storage for firmware or data in embedded systems and is accessed via a SPI-compatible interface.
Key points:
- Capacity: 16 Mbit (about 2 MB)
- Interface: standard SPI (read, write, erase operations)
- Operations: page program (commonly 256 bytes), sector erases (4 KB), block erases (e.g., 64 KB), and chip erase
- Features: write enable/disable, status register, write protection, hold and reset pins
- Packaging/grade: 8‑pin package, RoHS-compliant (suffix GR); operating voltage typically 2.7–3.6 V (variants exist)
- Performance: fast read with high SPI clock; low power modes
Common use cases include boot firmware storage, application code storage, and data logging in microcontroller-based systems.

Features

GD25Q16CEIGR features (concise):
- 16 Mbit (2 MB) serial Flash memory
- 2.7–3.6 V operation; low-power CMOS
- SPI-compatible interface with support for Dual/Quad I/O (DQ/QIO) modes
- High-speed clock up to 104 MHz (Single SPI; higher in Dual/Quad modes)
- 256-byte page programming
- Erase: 4 KB sectors; 32 KB and 64 KB blocks; Chip erase
- 3-byte addressing (4-byte addressing mode available for larger devices via mode entry)
- Data protection: block protection, WP#/HOLD# pins, status registers
- Endurance ~100,000 program/erase cycles; data retention ~20 years
- Deep power-down for very low current in sleep mode
- Temperature range: industrial -40°C to +85°C
- JEDEC ID and fast read features; RoHS-compliant packaging (8-pin)
Note: exact mode availability and speeds can vary by revision; refer to the datasheet for the precise electrical specs.

Package

GD25Q16CEIGR uses an 8-pin SOP (SOP-8) package, RoHS-compliant and lead-free.

Pinout

- Pin count: 8 pins (SOP-8/SOIC-8 package)
- Function: 16 Mbit serial SPI flash memory (non-volatile) for firmware/data storage; supports SPI read/write with sector/page/block/chip erase operations.

Manufacturer

- Manufacturer: GigaDevice Semiconductor Inc. (GigaDevice)
- What kind of company: A fabless semiconductor company that designs and markets flash memory ICs (e.g., SPI NOR flash, NAND flash) for embedded systems.

Application

GD25Q16CEIGR is a 16‑Mbit SPI NOR flash. Common applications:
- Boot and firmware storage for microcontrollers/SoCs
- Code storage and firmware updates in consumer electronics (routers, set‑top boxes, printers)
- Non-volatile data storage (configuration, calibration, logs, LUTs) in industrial, IoT, and automotive systems
- External memory for low-pin-count embedded devices requiring 3.3 V operation
